Diabetic cardiomyopathy (DCM) is one of the most common complications of diabetes mellitus and is a major threat to global health. As a key mechanism in the occurrence and progression of DCM, the inflammatory response persists throughout the entire course of the DCM. The Gaozhuo theory suggests that the basic pathogenesis of inflammatory injury in DCM is the Qi deficiency of spleen and kidney and Gaozhuo invasion, and divides the pathological process into three phases: Gaozhuo invasion, turbid heat damage to the channels, and turbid blood stasis and heat junction. Among them, the Qi deficiency of spleen and kidney and the endogenous formation of Gaozhuo represent the process of inflammatory factor formation induced by glucose metabolism disorders. Turbid heat damage to the channels refers to the process of myocardial inflammatory injury mediated by inflammatory factors, and turbid blood stasis and heat junction are the process of myocardial injury developing toward myocardial fibrosis and ventricular remodeling. As the disease continues to progress, it eventually develops into a depletion of the heart Yang, leading to the ultimate regression of heart failure. According to the theory of Gaozhuo, traditional Chinese medicine (TCM) should regulate inflammatory injury in DCM by strengthening the spleen and tonifying the kidney to address the root cause, and resolving dampness and lowering turbidity to treat the symptoms. If the turbidity has been stored for a long time and turns into heat, strengthening the spleen and tonifying the kidney, and clearing heat and resolving turbidity should be the therapy. If the turbidity, stasis, and heat are knotted in the heart and collaterals, strengthening the spleen and tonifying the kidney, and resolving stasis and lowering turbidity should be the therapy. TCM compounds and monomers can regulate the inflammatory response in DCM. TCM compounds can be divided into the categories for benefiting Qi to resolve turbidity, benefiting Qi and clearing heat to resolve turbidity, and benefiting Qi and activating blood to reduce turbidity. The compounds can inhibit upstream signals of inflammation and expression of inflammatory factors, improve the inflammatory damage to myocardium and blood vessels, myocardial fibrosis, and cardiac systole and diastole, and thus slow down the onset and progression of DCM.

Non-alcoholic fatty liver disease (NAFLD) is one of the most common complications of type 2 diabetes mellitus (T2DM), and hepatic stellate cell (HSC) activation is the key link in the progression of NAFLD to liver fibrosis. According to the theory of "Gaozhuo", spleen deficiency and Qi stagnation, along with Gaozhuo invasion, are the causes of NAFLD progression to liver fibrosis, which reveals the pathogenesis essence of HSC activation in traditional Chinese medicine (TCM). Among them, spleen deficiency and Qi stagnation are the root causes of the endogenous formation of Gaozhuo. Spleen deficiency indicates the insulin sensitivity decrease and glucose metabolism disorders, and Qi stagnation means the dysregulation of hepatic glucose and lipid metabolism, which creates the preconditions for HSC activation. Gaozhuo invasion is the direct cause of HSC activation, including three stages: Internal retention of Gaozhuo, turbidity and stasis stagnation, and toxic stasis and consolidation. Internal retention of Gaozhuo refers to the abnormal metabolism and deposition of hepatic lipids, as well as the microcirculatory disorders. Turbidity and stasis stagnation is the process by which lipotoxicity stimulates the transformation of HSC into myofibroblast (MFB), and toxic stasis and consolidation represent the secretion of a large amount of extracellular matrix (ECM) by MFB to promote the fibrosis. According to the theory of Gaozhuo and the activation process of HSC, syndromes for T2DM combined with NAFLD can be classified into spleen deficiency and Qi stagnation with internal retention of Gaozhuo, spleen Qi deficiency with turbidity and stasis stagnation, and spleen Qi deficiency with toxic stasis and consolidation. Clinically, the treatment principle is to strengthen the spleen and promote Qi, resolve turbidity, and eliminate blood stasis. Both TCM compounds and monomers can effectively inhibit the HSC activation. TCM compounds can be classified into categories for regulating spleen and harmonizing liver, resolving turbidity and removing stasis, and detoxifying and removing stasis. They mainly work by improving lipid metabolism, reducing lipid accumulation in the liver, alleviating inflammatory and oxidative stress responses, inhibiting the activation and proliferation of HSC, and reducing ECM deposition, thereby delaying the progression of liver fibrosis.

ObjectiveTo investigate the effect of Tougu Xiaotong capsules (TGXTC) on the regulation of chondrocyte PANoptosis, delay of chondrocyte degeneration, and improvement of the symptoms in knee osteoarthritis (KOA). MethodsIn vivo experiments: 50 male C57BL/6 mice were randomly assigned into five groups (n=10 per group): sham operation group, model group, low-dose TGXTC group (7.2 g·kg-1), high-dose TGXTC group (14.4 g·kg-1), and diclofenac sodium group (0.05 g·kg-1). Except for the sham group, KOA models were established in all other groups using the modified Hulth method. Following successful model induction, the TGXTC groups received daily oral gavage of 7.2 or 14.4 g·kg-1 for 6 weeks, while the diclofenac sodium group received 0.05 g·kg-1 solution daily over the same duration. Model evaluation was performed using Lequesne MG score; micro-computed tomography (micro-CT) was used to scan the knee, hematoxylin-eosin (HE) staining and safranin O-fast green staining were used to observe the morphology of cartilage, transmission electron microscopy (TEM) was used to determine ultrastructural changes of PANoptosis. Multiple immunofluorescence (IF) co-localization assays was performed to detect the co-localization of cleaved Caspase-3, receptor-interacting protein 3 (RlPK3), and the N-terminal domain of gasdermin D (GSDMD-N) in cartilage tissue, while western blot was employed to detect the expression levels of cleaved Caspase-3, RIPK3, and GSDMD-N. In vitro experiments: The knee cartilages of 4-week-old SD rats were isolated, and a chondrocyte in vitro culture system was established through mechanical digestion with 0.2% type Ⅱ collagenase. Second-generation chondrocytes were divided into three groups: the control group, the model group (pretreated with 10 mg·L-1 lipopolysaccharide (LPS) for 24 h followed by treatment with 1 μmol·L-1 nigericin for 4 h), and the TGXTC treatment group (pretreated with 10 mg·L-1 LPS for 24 h, followed by exposure to 1 μmol·L-1 nigericin for 4 h and subsequently treated with 100 mg·L-1 TGXTC for an additional 24 h). The levels of reactive oxygen species (ROS), apoptosis, necroptosis, and pyroptosis of chondrocytes were evaluated via fluorescence microscopy following staining with ROS detection, AO/EB and YO-PRO-1/PI staining kits. Transmission electron microscopy was utilized to investigate the ultrastructural changes associated with PANoptosis in cartilage tissue of KOA mice. Inflammatory cytokine levels (IL-1β and IL-18) were measured using ELISA. Western blot was conducted to assess protein expressions related to PANoptosis, including cleaved Caspase-3, cleaved Caspase-8, RIPK3, ZBP1, GSDMD-N, and NLRP3. ResultsCompared with the sham group, the Lequesne MG scores were significantly up-regulated(P<0.01) in the model group, and the pathological changes of cartilage were significantly, with joint spaces narrower, osteophyte formation increased, secere abrasion of cartilage surface. Ultrastructural analysis revealed pronounced chondrocyte apoptosis, necroptosis, and pyroptosis, along with markedly elevated expression of cleaved Caspase-3, RlPK3, and GSDMD-N in cartilage tissue (P<0.01). In addition, The mean fluorescence intensities of ROS, orange-red fluorescence in AO/EB staining, green fluorescence and red fluorescence in YO-PRO-1/PI staining were increased of chondrocyte in the model group (P<0.01) . The levels of inflammatory factors IL-1β and IL-18 in the supernatant were increased (P<0.01). The expression of PANoptosis related proteins (cleaved Caspase-3, cleaved Caspase-8, RIPK3, ZBP1, GSDMD-N, and NLRP3) were also significantly upregulated(P<0.05). Compared to the model group, the TGXTC group demonstrated a significant improvement in various parameters of mice. These included a reduction in the Lequesne MG score, an increase in joint space, a decrease in osteophyte formation, diminished cartilage damage, reduced release of ROS, and alleviation of apoptotic, necroptotic, and pyroptotic processes in chondrocytes. Additionally, mitochondrial swelling and endoplasmic reticulum dilation were also mitigated. The levels of ROS as well as IL-1β and IL-18 were significantly decreased (P<0.05). Furthermore, the expression levels of proteins associated with PANoptosis in cartilage tissue showed marked reductions (P<0.05). Similar results were observed in chondrocytes: cleaved Caspase-3, cleaved Caspase-8, RIPK3, ZBP1, GSDMD-N, and NLRP3 exhibited significant decreases as well (P<0.05). ConclusionTGXTC may mitigate chondrocytes degeneration and alleviate KOA symptoms by reducing oxidative stress and suppressing the activation of PANoptosis pathways.

AIM: To explore the effect of adiponectin(ADPN)on angiogenesis of human retinal microvascular endothelial cells(hRMECs)in high glucose(HG)environment and role of NOD-like receptor family pyrin domain containing 3(NLRP3)inflammasome.METHODS: The hRMECs were divided into six groups, including control group(without treatment), HG group: incubated with D-glucose, ADPN group: pretreatment with ADPN and then incubated with D-glucose, CY-09 group: pretreatment with CY-09(an NLRP3 inhibitor)and then incubated with D-glucose, Nigericin group: pretreatment with nigericin(an NLRP3 activator)and then incubated with D-glucose, Nigericin+ADPN group: pretreatment with nigericin and ADPN and then incubated with D-glucose. NLRP3 level was detected using Western blot analysis. hRMECs migration was measured using scratch wound healing assay. The tube formation of hRMECs was detected using Matrigel.RESULTS: The NLRP3 expression in hRMECs cultured in an HG environment was significantly increased(P<0.01), while ADPN and CY-09 reduced the elevated NLRP3(both P<0.05 vs HG group). Nigericin significantly increased NLRP3 levels(P<0.01 vs control group)which was reversed by ADPN(P=0.032 vs Nigericin group). hRMECs migration ability(P<0.001), and total master segments length and number of meshes increased in HG group(P<0.001)while decreased in ADPN and CY-09 groups(all P<0.01 vs HG group). The hRMECs migration ability and tube formation(total master segments length and number of meshes)in HG environment were significantly increased by nigericin(P=0.003), while ADPN inversed the change. CONCLUSION: ADPN alleviates the migration and angiogenesis of hRMECs under HG conditions.

Objective:
To understand the current status of short video addiction among vocational nursing students in higher vocational colleges (hereinafter referred to as "nursing students") and its related factors, so as to provide a reference for formulating online education programs in colleges.
Methods:
From March to May 2025, a stratified random sample of 2 223 nursing students from four vocational colleges in Henan Province was selected. Short Video Addiction Scale for College Students, Short form Egna Minnen av Barndoms Uppfostran for Chinese, Peer Rejection Scale, and University of California at Los Angels Loneliness Scale were used for investigation. Chi square test and multivariate Logistic regression analysis were used to explore the related factors of short video addiction among nursing students.
Results:
The detection rate of short video addiction of higher vocational nursing students was 26.95%, and the scores for avoidance, loss of control, inefficiency and withdrawal were (8.05±2.97) (10.24±3.09) (4.99±1.88) and (11.97±4.10), respectively. Multivariate Logistic regression analysis showed that sophomore year 2 ( OR=1.83, 95%CI =1.39-2.40), higher maternal education level (secondary school/vocational college: OR =1.34, 95% CI =1.06-1.68; college/undergraduate: OR =1.38, 95% CI =1.05-1.82), paternal overprotection ( OR=1.59, 95%CI =1.27-2.00), high peer rejection ( OR=1.40, 95%CI =1.19-1.66), and strong loneliness ( OR=1.57, 95%CI =1.07-2.28) were associated with a higher risk of short video addiction among nursing students (all P <0.05). Paternal affectionate and warm rearing style ( OR=0.82, 95%CI = 0.71- 0.95) was associated with a lower risk of short video addiction ( P <0.05).
Conclusions
The detection rate of short video addiction among nursing students is relatively high. Short video addiction is related to the nursing students grade, maternal education level, paternal overprotection and affectionate rearing style, peer rejection, and loneliness.

ObjectiveTo investigate the protective effects of Zuogui Wan (ZGW) decoction on nephrotic syndrome (NS) through the regulation of gut microbiota. MethodsThirty male Sprague-Dawley (SD) rats were randomly divided into five groups, with 6 rats in each group: The control group, model group, low-dose group, medium-dose group, and high-dose group. The NS rat model was induced by tail vein injection of 6.5 mg·kg-1 doxorubicin. After successful modeling, the control and model groups were gavaged with normal saline (10 mL·kg-1) twice daily, while the low- (50 mg·kg-1), medium- (100 mg·kg-1), and high-dose (200 mg·kg-1) groups were gavaged with ZGW (10 mL·kg-1) twice daily. All rats were administered at fixed intervals daily for 8 consecutive weeks. The therapeutic effects of ZGW on NS in rats were observed, and the optimal dose was screened. Renal and intestinal pathological changes in rats were examined. Fecal samples were collected, and 16S rDNA sequencing technology was used to detect the diversity and abundance of gut microbiota in each group. ResultsCompared with the control group, 24-hour urinary protein, serum creatinine, urea nitrogen, and cholesterol levels significantly increased in the model group (P<0.01), while serum albumin levels decreased (P<0.01). These changes were ameliorated in the treatment groups (P<0.05, P<0.01). Renal pathology revealed intact and orderly arranged glomeruli and renal tubules in the control group. In the model group, glomerular atrophy, widened mesangial areas, podocyte swelling, disordered renal tubular arrangement, and numerous casts were observed. Varying degrees of glomerular atrophy and disordered renal tubular arrangement were seen in the treatment groups. Specific protein assays revealed increased serum levels of kidney injury molecule-1(KIM-1) and α1-microglobulin (P<0.01), and significantly decreased levels of E-cadherin, Podocin, and Nephrin in renal tissues (P<0.01), along with a significant increase in transforming growth factor-β(TGF-β) (P<0.01) in the model group. In the treatment groups, serum KIM-1 and α1-microglobulin levels decreased, E-cadherin levels significantly increased (P<0.01), and TGF-β levels significantly decreased (P<0.01). Podocin and Nephrin levels increased in the high-dose group (P<0.05). Additionally, intestinal mucosal atrophy, epithelial cell edema, decreased goblet cells, and multiple inflammatory infiltrations were observed in the model group. The sequencing results of gut microbiota demonstrate that ZGW can significantly ameliorate intestinal dysbiosis in rats, restore the abundance of beneficial bacteria, and exert a profound influence on the compositional profile of gut microbiota. ConclusionZGW can alleviate renal injury in rats with nephrotic syndrome by improving gut microbiota and protecting the intestinal barrier.

OBJECTIVE:
To investigate the safety and effectiveness of using the Taylor spatial frame (TSF) based on the Ilizarov tension-stress principle for treatment of post-burn foot and ankle deformities in adults.
METHODS:
A clinical data of 6 patients with post-burn foot and ankle deformities treated between April 2019 and November 2023 was retrospectively analyzed. There was 1 male and 5 females with an average age of 28.7 years (range, 20-49 years). There were 3 cases of simple ankle equinus, 2 cases of ankle equinus, midfoot rocker-bottom foot, and forefoot pronation, and 1 case of calcaneus foot and forefoot pronation. Preoperative American Orthopedic Foot and Ankle Society (AOFAS) score was 45.3±18.2, 12-Item Short-Form Health Survey (SF-12)-Physical Component Summary (PCS) score was 34.3±7.3 and Mental Component Summary (MCS) score was 50.4±8.8. Imaging examination showed tibial-calcaneal angle of (79.8±31.5)°, calcaneus-first metatarsal angle of (154.5±45.3)°, talus-first metatarsal angle of (-19.3±35.0)°. Except for 1 case with severe deformity that could not be measured, the remaining 5 cases had talus-second metatarsal angle of (40.6±16.4)°. The deformities were fixed with TSF after soft tissue release and osteotomy. Then, the residual deformities were gradually corrected according to software-calculated prescriptions. TSF was removed after maximum deformity correction and osteotomy healing. External fixation time, brace wearing time after removing the TSF, and pin tract infection occurrence were recorded. Infection severity was evaluated based on Checketts-Otterburns grading. Joint function was evaluated using AOFAS score and SF-12 PCS and MCS scores. Patient satisfaction was assessed using Likert score. Imaging follow-up measured relevant indicators to evaluate the degree of deformity correction. Deformity recurrence was observed during follow-up.
RESULTS:
The external fixation time was 103-268 days (mean, 193.5 days). The mild pin tract infections occurred during external fixation in all patients, which healed after pin tract care and oral antibiotics. No serious complication such as osteomyelitis, fractures, neurovascular injury, or skin necrosis occurred. After external fixation removal, 3 cases did not wear braces, while the remaining 3 cases wore braces continuously for 6 weeks, 8 weeks, and 3 years, respectively. All patients were followed up 13.9-70.0 months, with an average of 41.7 months. During follow-up, none of the 6 patients had recurrence of foot deformity. At 1 year after operation, the AOFAS score was 70.0±18.1, SF-12-PCS and MCS scores were 48.9±4.5 and 58.8±6.4, respectively, all showing significant improvement compared to preoperative values ( P<0.05). Imaging follow-up showed that all osteotomies healed, and all distraction cases achieved bony union at 6 months after stopping stretching. At 1 year after operation, tibial-calcaneal angle was (117.5±12.8)° and talus-first metatarsal angle was (-3.3±19.3)°, both showing significant improvement compared to preoperative values ( P<0.05). Calcaneus-first metatarsal angle was (132.0±14.4)°, which also improved compared to preoperative values but without significant difference ( P>0.05). Except for 1 case with severe deformity that could not be measured, the remaining 5 cases had talus-second metatarsal angle of (18.0±6.4)°. And there was no significant difference ( P>0.05) between pre-and post-operative data of 4 patients with complete data. At 1 year after operation, 1 patient was satisfied with effectiveness and 5 patients were very satisfied.
CONCLUSION
The TSF, by applying the Ilizarov tension-stress principle for gradual distraction and multi-planar adjustment, combined with soft tissue release and osteotomy, can effectively correct foot and ankle deformities after burns, especially equinus deformity with contracture of the posterior soft tissues of the lower leg. There are still limitations in treating cases with tight, adherent scars on the dorsum of the foot that require long-distance distraction. If necessary, a multidisciplinary approach combined with microsurgical techniques can be utilized.

Abuse of amphetamine-based stimulants is a primary public health concern. Recent studies have underscored a troubling escalation in the inappropriate use of prescription amphetamine-based stimulants. However, the neurophysiological mechanisms underlying the impact of acute methamphetamine exposure (AME) on sleep homeostasis remain to be explored. This study employed non-human primates and electroencephalogram (EEG) sleep staging to evaluate the influence of AME on neural oscillations. The primary focus was on alterations in spindles, delta oscillations, and slow oscillations (SOs) and their interactions as conduits through which AME influences sleep stability. AME predominantly diminishes sleep-spindle waves in the non-rapid eye movement 2 (NREM2) stage, and impacts SOs and delta waves differentially. Furthermore, the competitive relationships between SO/delta waves nesting with sleep spindles were selectively strengthened by methamphetamine. Complexity analysis also revealed that the SO-nested spindles had lost their ability to maintain sleep depth and stability. In summary, this finding could be one of the intrinsic electrophysiological mechanisms by which AME disrupted sleep homeostasis.

Objective:To compare the effects of different automatic normal tissue objective(NTO)weights(WNTO)of Eclipse planning system on intensity modulated radiation therapy(IMRT)of fixed field for abdominal tumor.Methods:Twenty patients with rectal cancer and twenty patients with cervical cancer who received radiotherapy in The Second People's Hospital of Huludao from September 2022 to January 2024 were selected.5 groups of different plans[WNTO20,40,60,80 and 100]were respectively formulated for each patient.Among of them,the WNTO20 plan was control group,and other 4 groups were respectively WNTO40 group,WNTO60 group,WNTO80 group and WNTO100 group.Then,the differences in dosimetry and monitor units(MU)among 5 groups of plans were compared.Results:In the WNTO 80 and 100 groups of patients with rectal cancer,the conformation index(CI)values of target regions of them were respectively 1.02±0.04 and 1.00±0.03,all of which approached to 1,and the CI values of two groups were lower than that of control group,and the differences were statistically significant(t=15.986,18.422,P<0.05).The homogeneity index(HI)of WNTO 80 and 100 groups were respectively 0.09±0.12 and 0.10±0.14,which were higher than that of control group,and the differences were statistically significant(t=-1.371,-1.463,P<0.05).The 52Gy dose volume(Vmax52)of small intestine of the two groups were respectively(4.48±14.49)and(4.77±10.47)cm3,which were higher than that of control group,and the differences were statistically significant(t=-1.360,-2.005,P<0.05).The 30 Gy dose volume percentage(V30 Gy)values of the right femoral heads of the two groups were respectively(12.28±4.57)%and(10.96±4.17)%,which were lower than that of control group,and the differences were statistically significant(t=6.893,6.75,P<0.05).The 30 Gy dose volume percentage(V30 Gy)values of the left femoral head of the two groups were respectively(11.57±4.41)%and(10.17±3.78)%,which were lower than that of control group,and the differences were statistically significant(t=6.782,5.963,P<0.05).The MU value of WNTO100 group was(1254±93)MU,which was higher than that of control group,and the difference was statistically significant(t=-3.741,P<0.05).In the WNTO 80 and 100 groups of patients with cervical cancer,the CI values of target regions of them were respectively 1.03±0.32 and 1.02±0.03,all of which approached to 1,and the CI values of the two groups were lower than those of control group,and the differences were statistically significant(t=20.069,19.475,P<0.05).The HI values of them were respectively 0.07±0.05 and 0.08±0.01,which were higher than that of control group,and the differences were statistically significant(t=-12.445,-19.478,P<0.05).The V30 Gy values of the right femoral heads of the two groups were respectively(16.11±4.71)%and(14.90±4.56)%,which were lower than that of control group,and the differences were statistically significant(t=7.875,8.020,P<0.05).The V30 Gy values of the left femoral head of the two groups were respectively(15.21±3.71)%and(13.93±3.77)%,which were lower than that of control group,and the differences were statistical significance(t=7.617,7.436,P<0.05).The Vmax52 of small intestine of the two groups were respectively(0.82±1.10)and(4.47±8.81)cm3,which were higher than that of control group,and the difference was statistically significant(t=-2.985,-2.388,P<0.05).Conclusion:The WNTO80 is recommended for IMRT plan of radiotherapy on abdominal tumor,which can more quickly and better meet the assessment conditions of IMRT plan.
